| الوصف: | INTRODUCTION Acute mountain sickness (AMS) may develop in nonacclimatized individuals after exposure to altitudes ≥2500 m. Anecdotal reports suggest that endurance-trained (ET) athletes with a high maximal oxygen uptake (V˙O2max) may be at increased risk for AMS. Possible underlying mechanisms include a training-induced increase in resting parasympathetic activity, higher resting metabolic rate (RMR), and lower hypoxic ventilatory response (HVR). METHODS In 38 healthy, nonacclimatized men (19 ET and 19 untrained controls [UT], V˙O2max 66 ± 6 mL·min·kg vs 45 ± 7 mL·min·kg; P < 0.001) peripheral oxygen saturation (SpO2), heart rate variability, RMR, and poikilocapnic HVR were assessed at 424 m and during 48 h at 3450 m after passive ascent by train (~2 h). Acute mountain sickness was evaluated by AMS cerebral (AMS-C) score. RESULTS On day 1 at altitude, ET presented with a higher AMS incidence (42% vs 11%; P < 0.05) and severity (AMS-C score: ET, 0.48 ± 0.5 vs UT, 0.21 ± 0.2; P = 0.03), but no group difference was found on days 2 and 3. SpO2 decreased upon arrival at altitude (ET: 82% ± 6% vs UT: 83% ± 4%; ptime |
